Figure 4 Results of graphical representation of data
Based on the finding that the effect of the loop enters the
measurement, multi-factor ANOVA was used instead of the one-
factor ANOVA method. An evaluation of the results could then be
performed based on this method.
Looking at Table 5 with the results of the multi-factor ANOVA
method, it can be stated that the number of points does not affect the
achieved values. [1,9,10] However, this is true only if the diameter
of the part is evaluated. What cannot be overlooked, however, is the
need to correct the results when the measurement is performed in a
loop. All this can be stated on the basis of a model that works with
an accuracy of 94%.

For confirmation, the evaluation was plotted in a graph (Graph 1).
Here, it is possible to clearly identify and state that the number of
points has almost no effect on the measurement.
Graph 1 Interval plot of ring diameter vs number of points 95 % CL
for the diameter
The same is true if we look at the graphs for evaluating the
diameters for the small and medium gauges. See graphs 2 and 3.
